Even colder weather coming with a snow potential.

A Special Weather Statement from the NWS Portland.

Another system will drop south out of British Columbia today, bringing snow to the coast range, the Foothills, and the Cascades this afternoon and tonight. Snow levels will generally be between 1000-1500' but may fall to 500' in southwest Washington tonight. Winter Weather Advisories for this afternoon and tonight have been issued for the Oregon Cascades and Foothills as well as the central Coast Range.

A stronger system will drop south out of British Columbia on Monday allowing more significant cold air to filter into southwest Washingtonm and Northwest Oregon. Snow levels will lower to near the valley floor late Monday afternoon thru Monday night, with the potential for light accumulations as the system drops to the south. The Coast may also see some snow by Monday night. The best threat for significant low elevation snowfall will be the Gorge where 2-4" may fall. The Coast Range and Foothills may see 3-6" of new snow, with 6-12"in the Cascades. Lighter amounts are expected over southwest Washington with the heavier amounts further south.

Low temperatures in the valley are likely to drop into the 20s Monday and Tuesday nights, with slow moderation to follow for the latter half of the week. After Monday night it appears drier conditions are in store as high pressure builds over the region.

Now would be a good time to make preparations for colder temperatures and possibly snow in the lowlands.
